Welcome!

Arun

I am postdoctoral researcher at Sterrewacht Leiden (Leiden Observatory), which is the astronomy department of the Leiden University. I am involved in the research groups of Prof. Henk Hoekstra and Prof. Koenrad Kuijken, where I focus on improving galaxy image simulations for Euclid and KiDS lensing surveys.

I obtained my Ph.D. from the Department of Physics at Carnegie Mellon University in the Fall of 2016. Specifically, I was associated with the McWilliams Center for Cosmology, where I worked with Prof. Rachel Mandelbaum on problems related to gravitational weak lensing. Visit my research page to see the problems I am working on and my publications so far.

I earned my Masters degree in Physics from Carnegie Mellon University in the summer of 2013. I earned my Bachelors degree in Electrical Engineering from IIT Madras with a minor in Physics in the summer of 2011.

You can find my curriculum vitae in PDF format.
